The Investigation of the Coal Ignition Temperature in

Abstract. The oxygen-enriched Circulating fluidized bed (CFB) combustion technology is a new method to reduce CO 2 emissions. The coal ignition temperature, T i, in an oxygen-enriched CFB boiler is an important parameter for designing the startup burner and for choosing the operating strategy during the startup process.Comparing with the complicated operation in real oxygen-enriched CFB boiler

Coal & Air

In a super critical coal plant steam is not created. Liquid water becomes a supercritical fluid in the superheaters at a pressure of greater than 221 bar and a temperature of greater than 400C. Therefore there is no steam drum. In a supercritical boiler warmed feedwater passes directly into the downcomers.
